Setting up the radio-controlled clock
− Place the radio-controlled clock as close to the
window as possible. The device usually receives
the strongest signal there.
About the time signal
transmitter DCF77
This radio-controlled clock receives its radio signals
from the time signal transmitter DCF77. This
broadcasts the precise and official time of the Federal
Republic of Germany on the long-wave frequency
of 77.5 kHz. The transmitter is located in Mainflingen
near Frankfurt am Main and, with its range of up to
2000 km, supplies the majority of radio-controlled
clocks in western Europe with the necessary radio
signals.
When you power up the radio-controlled clock, it
switches to Reception mode and searches for the
signal from the DCF77 transmitter. If the time signal is
received in sufficient strength, the time is displayed.
The radio-controlled clock switches on several times
a day and synchronises the time with the radio signal
from the transmitter DCF77. In the event the signal
is not received, e.g. during a strong storm, the clock
continues to run precisely and then switches to
receiving mode again at the next scheduled time.
